Help with a macro for passwords

[baldi]

I have a workbook that has 3 sheets. On sheet 1 cell D7 is where I enter a password to get into sheet 2. sheet 3 is where I store the names and passwords. I need help writing a macro to check if the password entered in Cell D7 on sheet 1 matches the password in the chart on sheet 3. the password are in column D on sheet 3

Thanks for the Help in advance.

I suspect you want more than you asked for. For example, you didn't tell us what you want to happen if there's a match or if there's no match. But, let's start with the sheet code below which you can try and then ask for modifications to include things you want but didn't ask for.

This is sheet code to be installed in Sheet1 following the steps below. The code will run automatically whenever a change is made to cell D7 on Sheet1.
To install sheet code:
1. Right-click the worksheet tab you want to apply it to and choose 'View Code'. This will open the VBE window.
2. Copy the code below from your browser window and paste it into the white space in the VBE window.
3. Close the VBE window and Save the workbook. If you are using Excel 2007 or a later version do a SaveAs and save it as a macro-enabled workbook (.xlsm file extension).
4. Make sure you have enabled macros whenever you open the file or the code will not run.

Private Sub Worksheet_Change(ByVal Target As Range)
Dim n As Variant
Set Target = Target.Cells(1, 1)
If Not Intersect(Target, Range("D7")) Is Nothing Then
    If Target <> "" Then
        n = Application.Match(Target.Value, Sheets("Sheet3").Range("D:D"), 0)
        If Not IsError(n) Then
            MsgBox "There's a match on Sheet3, col D to Sheet1 cell D7"
        Else
            MsgBox "No match on sheet3, col D to sheet1 cell D7"
        End If
    End If
End If
End Sub
